Abstract

Background
Although appropriate dietary adjustments in hemodialysis (HD) patients are important, most HD patients have difficulty adhering to dietary therapy due to the stress of a restricted-food diet or loss of appetite, which eventually leads to malnutrition and other complications. The dietary intake of HD patients stratified by nutritional status has not yet been studied.
Methods
In total, 111 HD patients from five dialysis centers were stratified into 2 groups based on the Subjective Global Assessment: the well-nourished group and the poorly nourished group. The 7-day dietary intake and food behaviors of the two groups were compared. Logistic regression analysis was performed to reveal the factors associated with poorly nourished status.
Results
The 7-day dietary survey showed a lower intake of total calories and protein and a higher intake of sodium and potassium than in the standard recommendations, but there were no differences between groups. The poorly nourished group ate fried food significantly more frequently than the well-nourished group. Moreover, higher hip and waist circumferences were significantly associated with poorly nourished status.
